Ðề: Đồ án thiết kế Đường của em có 1 số phrase khó quá!
Sau đây tôi tìm được một đoạn về standard axle,
theo đó thì nó khác với, không trùng với unfactored trong trường hợp này, vì bản chất của nó có khác đi so với cái tôi phân tích ở trên (bên xây dựng ít có trường hợp như vậy). có lẽ bạn sportkid có thể tham khảo thêm và có thể dùng "standard axle load" được.
Standard axle
An axle carrying a load of 8200kg (18,000 lb). The legal axle limit in the UK is 11250kg for a non steering axle and 6250kg for a steering axle. Vehicle designers usually employ all of the legal weights. In design, we need to express axle loads in terms of standard axles. We do this by dividing the each vehicle axle load by the standard axle value and raising the result to the power 3.75. This means that a legal maximum non-steering axle applies 3.3 standard axles and a legal limit steering axle applies 0.4 standard axles. A full double decker bus would weigh about 15,000 kg, with 6000kg applied through the front axle and 9,000kg applied through the rear axle. Calculations show the number of standard axles for such a vehicle to be 2.3. An empty double decker bus would weigh 10,000 kg with 4000kg applied through the front axle and 6,000kg applied through the rear axle. This vehicle would apply 1.1 standard axles. It might be concluded that a service of double decker buses would each apply 2 standard axles as an average.
Cumulative traffic
The number of standard axles a pavement is designed to carry, measured in millions of standard axles (msa). Sometimes, the term cumulative number of standard axles (csa) is used, particularly when the total number of standard axles which will traffic a road throughout its life is being expressed. These figures are determined by multiplying the anticipated number of vehicles per hour by the number of trafficked hours in a day, then by the number of days for which the road is being designed. Finally, the figure is multiplied by the number of standard axeles per vehicle. It may be necessary to consider a mix of vehicles.
